Consider a particle in a box with an infinite potential outside the box.

a) Calculate the energies, eigenfunctions using a box extending from 0 and L.

b) A Helium-Neon laser emits light of wavelength 632.8 nm. If this light is due to transitions from the n = 2 to the n = 1 state of an electron in a box, find the width of the box.

Summary

The question belongs to Physics and it is discusses about calculation of energies and egien functions using a box extending from 0 to L and also calculating the width of a box with helium-neon laser being emitted in the box.

Hello Allison,I love the 2nd image that you did! I also, had never heard of SumoPaint, is something that I will have to exolpre a bit! I understand completely the 52 (or so) youtube videos that you probably watched. Sometimes they have what you want, sometimes they don't! However, it is always satisfying when you are able to produce something that you have taught yourself. Great job!Debra 0 likes

WHAT OUR STUDENTS SAY

Emily Donaghue: With the course load and the pressure of submitting multiple assignments at the same time I was hardly getting any real information about the subject. My entire time was spent in running from pillar to post trying to complete the various assignments. Once I took the services of HwA for my power systems engineering assignment I was thoroughly impressed with their professionalism and quality and signed up for their package for the entire semester.

I used to get really confused with the acid-based
reactions and alkaline reactions when I approached HwA. From there onwards, I
took regular help and got enormous benefits.

I
had no clue about how to write a qualitative research paper on Faulkner and so
I approached HelpwithAssignment.com. I was also not sure whether they could help me or not but to
my surprise they started asking the right kind of questions to me. When I
clarified them with my professor, she was impressed and told me that I
understood the concept of a research paper. The rest of it was a walk in the
park. With my professor’s inputs they provided an excellent research paper and
help me get an A

The tutoring that I received was also substantiated by the finance tutor with the help of finance text books and notes. The notes had proper referencing which helped me write my finance assignment so much better. Could not have asked for better online finance tutoring and am definitely going to recommend your services to my friends and juniors.

From my undergraduate course till my master
degree, I have been a regular client of HwA. The experts around here not only
help you with the solutions of particular assignment but also at the same time
helps you clear the concepts. It is like a marvellous bond and connection I
share with this website.
